POTATO HEALTH BENEFITS,
NUTRITION VALUES
In 18th century, potatoes were introduced to North America  via Irish immigrants, however their origin is
South America. Over 7,000 years ago, potatoes were first cultivated in the Andes Mountains. Many kinds
of potatoes are seen today, but the most common of these are the russet, round white, and the red
potato. Potatoes are tough and durable, store well, and have an impressive nutritional content including
being a rich source of fiber, potassium and vitamin C. Like other fruits and vegetables, potatoes are a
low calorie food and are free of fat, cholesterol, and sodium. However, the leaves and stems of a potato
plant are poisonous and may cause illness when ingested.

POTATO HEALTH BENEFITS

ANTI-OXIDATIVE ACTIVITIES
The antioxidative activities of anthocyanins from purple sweet potato have been  demonstrated. [2]

Does potato or sweet potato benefit people at risk of cancer?

French fries are bad for our health. In 2008, Flood A [flood@epi.umn.edu] and other researchers from
University of Minnesota studied the correlation between dietary patterns and colorectal cancer in about
490,000 middle-aged Americans. They found that dietary patterns characterized by a low frequency of
meat and potato consumption and frequent consumption of fruit and vegetables and fat-reduced foods
are consistent with a decreased risk of colorectal cancer. [3]

How are about potato extracts or sweet potatoes? Consumption of sweet potato and vegetables
reduced the odd of gallstone cancer in a study of 165 patients [A1]. And, there are two cell studies
supporting the idea that sweet potatoes may benefit people at risk of certain types of cancers. [6, 7]
Recently, a report from University of Mar del Plata, Argentina, has caught my eye. The researchers
showed the cytotoxic activity of potato aspartic proteases induced apoptosis on Jurkat T cells after a
short time of incubation in a dose-dependent manner. [1] Almost at the same time, Dr. Reddivari L and
research fellows Texas A&M University reported the anti-cancer activities of wild potato extracts on
human HT-29 colon and LNCaP prostate cancer cell lines in vitro [2] Dr. Reddivari L further demonstrated
that the cytotoxic activities of potato extract/ anthocyanin fractions in cancer cells were due to activation
of caspase-independent apoptosis. [5]

Researchers from Istituto di Scienze delle Produzioni Alimentari, Italy, reported that potato extracts
inhibited proliferation of human mammalian cancer (MCF-7) cells in a dose-dependent manner. [4] And,
this group used methanol/water or phosphate buffer to prepare the extracts. Based on these studies, I
won’t chop the potatoes into strips, deep-fry the strips in oils and then eat.

CHOLESTEROL LOWERING EFFECTS
Potato has been demonstrated to lower serum cholesterol. [3] Sweet potato was found to be effective
binder for cholesterol in a vitro study. [4]

Availability, Selection and Storage
Potatoes are grown across the United States and are available year round. Store potatoes in a cool, dry
place. Sunlight can cause the skin to turn green; if this occurs the skin must then be peeled off before
consuming. Most of the nutrients are contained right below the skin, so avoid peeling when possible.
Besides fresh potatoes, other forms are often available as well, including
• Refrigerated pre-cut fresh potatoes
• Frozen potatoes
• Canned potatoes
• Dehydrated potatoes

When choosing potatoes, be sure they are firm, smooth, and the color they are supposed to be.
Softness, a green tinge, or wrinkly skin may indicate a potato that is past its prime.

Preparation
Potatoes should be thoroughly washed with clean tap water and scrubbed lightly before preparation.
Any sprouts or eyes growing from the potato should be cut out. The skin can be removed or
left on depending on use.

Common methods of preparation include boiling, baking, microwaving, mashing, frying and grilling.
Consuming baked and grilled potatoes with the skin left on provides the most nutrients.

Include potatoes in your variety of daily colorful fruits and vegetables!

Start a vegetable garden and plant potatoes, they are easy to grow!

Wash and poke holes in a raw potato and microwave for about 4
minutes for a fast, tasty low-calorie snack.

Add cut-up boiled potatoes to stews and vegetable soups.

Wrap baking potatoes in foil and put them on the grill and add to a
summer meal.

Boil and mash potatoes for an all time favorite dish.

Slice potatoes into strips, season, and bake in the oven for healthy,
homemade French fries.
